Can’t tell what’s wrong with this plant

[Purfict]

About 2 weeks into flower, and it’s going pretty well. The only issue is this one plant in my tent looks very stressed out and I can’t figure out why. It’s leaves are warped almost like it has a fungal gnat infection, but it’s been a week and there isn’t a single other plant in the tent showing stress and not a single gnat has been seen either by me or on traps. Clearly they’re super stressed out, but it’s only the one plant.

That is overwatered or prolonged hot and humid. It is possible that she is in a hot spot or moist spot where when the fan sucks the humid air to disperse, that plant is getting hot humid air rushing over it. I see that exact leaf edge droop when humidity is prolonged or stagnant from night/day and temps have a small swing or prolonged low swing of temps coupled with low swing of humidity. Or like I said she is stuck in a pocket where the heat and humidity is greater than the rest. It is sitting next to the fan and therefore I can see all the airflow from the fan circling back to that plant and possibly heat/humidity soaking her?

I had thought that, so turned the fan off for about 2 days now. However, I do have an inline fan that enters the tent from there, maybe it’s that? I am battling humidity in that tent, got the dehumidifier going 24/7. That could be it

yes sir it is the humidity!

Even with the dehumidifier going, it’s sitting at 65. I’ll have to find some small tricks to get humidity down even further.

Bigger dehumidifier helps.
I ran into this same leaf signal when I wasn’t able to reduce night time humidity below 58. You want humidity low at night. Day time it can be 60s and be great. It was the night time humidity that needed to be dropped to 45-50 that corrected my issue.

I had to crank up my dehumidifier and hook up continual drain on the dump to achieve target. I have a dehumidifier rated above the lung room sq footage.

That’s the issue I face, my lung room is an entire unfinished basement that’s entirely open, 1000+ square foot. I found the humidity was way too high when I tried drying outside of a tent, it sits at around 70%. Maybe this summer I can try to just build one room to help.

You could make a plastic or cardboard box around the intake of the dehumidifier and have it connected to the tent. When the dehumidifiers fan is on, testing the air, it will suck and read the tents humidity that way. And the exhaust blowing out across the basement. At night you probably can reduce exhaust fan speeds because your dehumidifier will be sucking air while operating if done this way.

What I’ve been doing is just turning off the exhaust fan at night and just letting the fans in the tent run. Dehumidifier is going 24/7
